XD6131A401MR-Q

Supervisors Overview

The XD6131A401MR-Q is a voltage detector manufactured by Torex Semiconductor. It features an open-drain or open-collector output and monitors a single input channel with a threshold voltage of 4.0V. The device supports manual reset functionality and includes a watchdog timer. It operates within a supply voltage range up to 6V and maintains performance across a temperature range of -40°C to +125°C. The component is housed in a surface-mount SOT-26 package.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability
• Manual reset capability for controlled recovery
• Open-drain or open-collector output configuration

Supervisors Applications

• Battery backup switch monitoring
• Microprocessor reset circuits
• Portable equipment power management

Supervisors Procurement Notes

Verify the specific suffix MR-Q against official Torex documentation to confirm AEC-Q100 automotive qualification status. Ensure the ordering code matches the required threshold voltage and package type. Cross-reference datasheet revisions to confirm pinout compatibility and electrical characteristics before integration into final designs.

Supervisors Selection Notes

Select this component when a dedicated voltage monitor with integrated watchdog and manual reset is required. The SOT-26 package suits space-constrained applications. Verify that the 4.0V threshold aligns with the monitored rail. Confirm operating temperature requirements fall within the specified industrial range.

Supervisors Part Context

This part belongs to the XD6131 series of supervisory circuits from Torex Semiconductor. The series provides precise voltage detection with additional safety features like watchdog timers. These components are designed for reliable operation in portable and automotive electronics where power integrity is critical.

Supervisors Replacement Considerations

Check for XD6131 variants with different threshold voltages or output types. Verify package compatibility with existing footprints. Confirm functional equivalence regarding watchdog timeout periods and reset delay times.
